Abstract: An electrical outlet has socket openings for insertion of contact pins of an electrical plug therein, a closure element that selectively closes or opens the socket openings, and a latching element that selectively latches or unlatches the closure element. The closure element slides perpendicularly to the insertion axis. The latching element includes a latching pawl that is flexibly deflectable parallel to the insertion axis, between a latched position for engaging the closure element and an unlatched position for releasing the closure element. An unlatching pin of an adapter is inserted to deflect the latching pawl to disengage it from the closure element. This unlocks the receptacle for use. Then the contact pins of the plug may be inserted through holes in the adapter and into the socket openings to press sloping surfaces of the closure element to slide the closure element to the open position.

Abstract: In a method for generating an identifier for an audio signal including a tone generated by an instrument, a discrete amplitude-time representation of the audio signal is generated at first, wherein the amplitude-time representation, for a plurality of subsequent points in time, comprises a plurality of subsequent amplitude values, wherein a point in time is associated to each amplitude value. Subsequently, an identifier for the audio signal is extracted from the amplitude-time representation. An instrument database is formed from several identifiers for several audio signals including tones of several instruments. By means of a test identifier for an audio signal having been produced by an unknown instrument, the type of the test instrument is determined using the instrument database. A precise instrument identification can be obtained by using the amplitude-time representation of a tone produced by an instrument for identifying a musical instrument.
